I have absolutely been joining other veterans in preparing our SHTF knowledge base.
When an army forages, it has to know where the supplies are. Preppers are the supply depots.
This is related, but might not be for this thread. How much ammunition needs to be stored, how does the ammo get stored and when you are practicing, how many rounds do you typically shoot?
I’m not really planning for prepping, however I am doing small things like hoarding seeds and whenever I can get heirloom seeds, I stock up on them. When I was a kid, my father told me if there is ever a breakdown in society, seeds will be currency. This is 55 years ago.
